| Part   | Type                             | Description                                             |
|--------|----------------------------------|---------------------------------------------------------|
| result | `Double</api/data_types/double>` | Constant indicating the major and minor version number. |

## Notes

The format is the four digit year of the release followed by a period followed by the release number.

You can use <span class="title-ref">XojoVersion</span> in an `#if</api/compiler_directives/if...endif>` statement to determine whether a use is running a particular version of Xojo. Based on the result, you conditionally compile code that is available only for that version.

## Sample code

The following line displays the version of Xojo being used:

``` xojo
MessageBox("You're using version " + XojoVersion.ToString)
```

The following includes code only for applications built using Xojo version 2017 Release 1 or above.

``` xojo
#If XojoVersion > 2017 Then
  ' include code here
#EndIf
```
